A broadband metamaterial cylindrical lens antenna
Chinese Science Bulletin, 2010 We present a Luneberg-like cylindrical lens antenna experimentally using metamaterials. The cylindrical lens antenna with a broad bandwidth is made up of the non-resonant I-shaped metamaterial structures. The near-field distributions of the metamaterial lens antenna are measured using a two-dimensional near-field microwave scanning apparatus, and agree

Gaussian Beam Propagation through a Metamaterial Lens
Universal Journal of Applied Mathematics, 2014 We study a Gaussian beam propagation through a metamaterial lens by direct numerical simulations using COMSOL. We find that a metamaterial lens can deflect the beam significantly by either adjusting the shape of the lens or increasing the dielectric permittivity of the metamaterials.
